I agree about blogging vs. chatting. One of the most interesting things I've seen on Steemit is the growth of activity in comments. In the earlier days with a much smaller user base, there were few comments even on the top paid posts. In fact comments were so neglected that there was at one point a proposal to explicitly subsidize comment posting with a dedicated portion of the reward pool. That proposal was dropped, but nevertheless, as the user base grew, comments have taken off to where most decent posts, whether highly rewarded or not, generate a significant tree of discussion and many good ideas are developed in comments.

Anecdotally I hate blogs that disable comments and usually don't return to them more than once or twice. Whether I comment or not, I still want to see what others have to say about the post, and if the poster isn't allowing comments that could potentially challenge their claims, I'm less willing to take what they have to say seriously. The days of one-way information dissemination are over.

Overall this was a good post with useful analysis of the competitive landscape.
